Started taking birth control pills for the first time this month. My doctor told me to start taking them whenever to help with my periods. I started the next day (a friday which was not what the directions for the pills said to do). I have 6 pills left and have already started a heavy period. Is it messed up because my body is adjusting to the hormones or because I took the pills wrong (the directions said to start the sunday after my period and I started the friday after).
